Description
Living up to its name, Rhododendron ‘Garden Rainbow,’ a deciduous azalea, shows off abundant clusters of large flowers in a rainbow of yellow, orange, and pink shades, all in the same cluster! Depending on the location, the flowers come in late spring to early summer and are sure to be a favorite of butterflies and other beneficial pollinators. At 5 feet tall and 4 feet wide when all grown up, Garden Rainbow is a good fit as an accent specimen in smaller garden spaces, home foundation plantings, and containers, or in groupings in landscape, flowering shrub, or woodland borders. It is sure to be a conversation piece!
Landscape & Garden Uses
Growing 4 to 5 feet tall and 3 to 4 feet wide, the Garden Rainbow Azalea is ideal for use as an accent specimen in smaller garden spaces and containers or in groupings, or as a natural hedge in partially shaded woodland, landscape, and flowering shrub borders. Garden Rainbow is a fine addition to Azalea and Rhododendron Gardens, woodland gardens, cottage gardens, and butterfly and beneficial pollinator gardens.
Spacing: 3 feet apart for a solid hedge or grouping; 7 feet or more apart for space between plants
Growing Preferences
Garden Rainbow Azalea is very easy to grow in moist but well-drained soil of average to high fertility. Garden Rainbow performs well in full sun in the northern USDA Zones where it grows but will appreciate some shade or filtered sun in the afternoon in the deep South. Some suggest full sun tolerance throughout the zones where it is listed hardy, however, we always like to play it safe so as mentioned a break from direct afternoon sun in hotter climates. Once established plants are quite drought tolerant, requiring supplemental water only during prolonged periods of dry summer weather. Native azaleas are very low-maintenance, requiring little if any pruning. That said, occasionally we might prune a stray branch that is spoiling the natural form of the plant.
